I use it to read magazines I zipped up and then changed the ectension to cbz. I hope the fix also makes the compressed rar files with cbr extension. Would be nice. It is a bummer they screwed up the "fix".

What gets me is that QA "should" have at LEAST been given a LIST of file formats that the Nook can handle and then attempted to open each one before the software update went live. This is what I would call a bare minimum test. BTW - I have been using Perfect Viewer and it is about the best of about 5 that I have tried. Of course it's not Full Screen like the default reader "WAS" but hey, at least one can read comics. Also - one more thing. This piece of info GREATLY opened up my comic reading experience on the Nook and should be more common knowledge that what it is. The CBZ container can have MULTIPLE comic folders inside of it - not just a single one. I have 1GB files FULL of series and I don't have to go looking for the next comic in the series for weeks. When you finish one you'll move to the next folder in the container. I'm sure the CBR format is the same. So throw multiple folders into the CBZ - whatever makes sense to you - sit back and enjoy reading for months without having to find another one. I dropped from almost 2,000 separate files that were "Books" down to < 100, making my Books List MUCH easier to navigate and search.
